The leader of the band passed away in 2013 due to cancer. Ulala Session talked about their tragic loss on the February 28 broadcast of 'Idol Party'.

Park Seung Il stated, "There was a lot of trouble with our agency after Yoon Taek hyung left. I drank a lot and eventually I reached the point where I couldn't make a sound because I was screaming after drinking. I also developed stage fright." 

MC Kim Joon Ho asked how he overcame the struggles and Park Seung Il answered, "I was able to overcome it thanks to Myung Hoon. I had to lead the team but I was always drinking so Myung Hoon coldly snapped and told me that he wanted to do music with someone better than me."
